GNU Octave is a high-level language, primarily intended for numerical
computations.  It provides a convenient command line interface for solving
linear and nonlinear problems numerically, and for performing other numerical
experiments using a language that is mostly compatible with Matlab.  It may
also be used as a batch-oriented language.

These optional dependencies will be used if found:
* BLAS
* LAPACK
* glpk
* FFTW
* qhull
* HDF5
